measure 后邊跟具體測量值或形容詞時一般作系動詞.后邊跟測量的物體對象時才可做及物動詞用.這里是measure做系動詞的情況,所以選measuring不選measured.
例句：
using a ruler to measure a piece of paper
an instrument for measuring air pressure
mental abilities measured by IQ testing
He's being measured for a new suit.
His success cannot be measured solely on the basis of his popularity.
The cloth measures 3 meters.
The room measures 15 feet wide by 30 feet long.你的句子沒有完全打出來，沒法猜測came out 的意思和句子成份。
再說了，這里肯定不是定語后罝。后置的話是動詞現(xiàn)在分詞或者動
詞過去分詞而非你這里的動詞過去式形式。
